I was considering starting a thread on this thanks boreI watched s4 last year, then borrowed s1 from the library. Two episodes into s2 now, great timing as I have a baby up for several night feeds! Really intrigued as to who the protected witness is.

I've just got back from my exercise class, I'm about to have a shower and then watch my first ever episode (s1 e1) in my pyjamas and then plan to watch all 4 seasons from iPlayer over Christmas, exciting!!
